Filed: 1988-04-27
Abstract: PURPOSE:To obtain an always stable cleaning function by providing a return preventive member for prohibiting the back flow of a toner once stored in a storage part to the side end part of the storage part of a carrying section. CONSTITUTION:The residual toner remaining on the surface of an image carrying body 4 without contributing to transfer is scraped by a cleaning blade 2 and is successively carried above the blade 2 and a blade supporting plate 1 on progression of an image forming stage.

Title: Dielectric detecting device
Inventor: AOKI KOUJI
IPC: G01D5/24
Filed: 1992-04-23
Abstract: PURPOSE:To eliminate the erroneous confirmation of 'presence of person' and 'absence of person' and detect a failure in a circuit by comparing the absolute value of the difference between the electrostatic capacity data when a switch is in OFF state and an initial set value with a standard value. CONSTITUTION:A detecting circuit IC1 is formed of a gate array to detect a change in the electrostatic capacity of a capacitor CA and control the start and stop of a judging circuit IC2. The judging circuit IC2 has a microcomputer to judge the presence of a person on the basis of the output of the detecting circuit IC1. The judging circuit IC2 stores the electrostatic capacity data when a switch SW1 is in OFF state as an initial set value. Thus, since a failure such as the release of an input signal detecting low pass filter FL1 is judged, for example, when the circuit characteristic of the detecting circuit IC1 is largely changed when the absolute value of the difference between the electrostatic capacity data when the switch SW1 is in OFF state and the initial set value is a first standard value or more and less than a second standard value, the presence of the person is never erroneously confirmed.

IPC: G01N27/16
Filed: 1987-04-28
Abstract: PURPOSE:To use a contact combustion type CO sensor stably with time by transiently increasing element current at the time of turning on a power source. CONSTITUTION:A catalyst combustion type gaseous CO sensor is heated to a high temp. for about 10sec to expel the components absorbed on a catalyst during low-temp. use and to activate the catalyst so that the deterioration in the sensitivity of the sensor output with time is prevented. Charging of a capacitor 1 in a heat-up circuit (b) is started and a comparator 2 turns off and a comparator 3 on when the power supply is turned on. The voltage across the sensor is so set by regulators 3, 5 that the element temp. attains >=40 deg.C. The comparator 2 turns on and the comparator 3 off upon completion of the charging and, therefore, the voltage across the sensor is settled at the specified ordinary operating voltage after the determination by the regulators 4, 5. The time for heating up is adjusted by setting of a constant.
